(01. 15 -1 e) l g This invention relates to suction or vacuum cleaners of the type used for cleaning floor covering such as rugs, as well as for cleaning furniture.

draperies, and the likerand an. object of the invention is to improve generally upon such types Qcf cltaners as are now known and used.

The invention-together with its objects and advantages will be. best understood from a study ofthe following description taken in connection with the accompanying drawings wherein:

f Figure 1 is-a top, plan view of a. suction or vacuum cleaner embodying the features of the present invention with certain parts of the casing broken away and shown in section.

- ;'Figur 2 is a longitudinal sectional view taken substantially onthe line 2--2 of Figure 1.

Figure 3 is a front elevational view of the cleaner. I I 7 1 Figure 4 is a side elevational view showing a slightly modified formof cleaner. I t Figure 5 is a fragmentary bottom plan view illustrating a third modified form of cleaner casing. p

Referring more in detail to the drawings it will be seen that 5 indicates generally the casing of the suction or vacuum cleaner.

In accordance with the present invention the cleaner casing 5 is composed of a pair of longitudinally separable sections including a substantially cylindrical section 6 and a section I that gradually tapers towards the rear thereof.

At the joint between the sections 6 and 1, section 6 is provided with an integral annular socket i that receives the largest end of the section I; and the sections 6 and l are detachably secured together through the medium of latches 9 pivoted on the section 6 as at Ill and cooperable with keeper lugs It provided on the section I as shown.

At the front of the casing, casing section 6 has formed integral therewith a. nozzle l2.

The casing section 6 is also provided at opposite sides thereof with arms l3 in the lower ends of which are Journaled axles [4 on which are mounted supporting wheels 5.

The casing section I is similarly provided at opposite sides thereof with arms H5 in which are journaled axles ll upon which are mounted wheels it that are preferably of smaller diameter than the wheels l5.

Further the cleaner is equipped with a suitable handle it the fork 26 of which straddles the casing and at the legs of the fork there are provided eyes 25 that embrace the axles l4 and provide a pivotal connection between the handle and the vacuum cleaner.

Mounted in the casing section 6 and supported therein by vertical brace rods 22 and horizontal brace rods 23 is an electricmotor 24.

0n the forward end of the motor shaft 25 is a suction fan 26, while on the rear or opposite end of the shaft 25 is an impeller fan 21'.

The casing section I provides a. chamb'erfor the dust-receiving bag 28 that may be of any suitable material and is shaped confonnably to the shape of the casing section 1. f

At the mouth or open'end thereof the bag 28 has a portion thereof folded over the edge'of the casing section I so as to be clamped'at the mouth thereof within the confines of the joint/between the casing sections 6 and 1 as shown in Figure 2.

The bag 28 at the closedend thereof is anchored in position through the medium of a'suitable spring 29, and to facilitate manipulation of the bag to empty the'contents' thereof there is provided interiorly of the bag adjacent the mouth thereof a finger-ring 30. V

The ring 30 is secured to the bag 28; and one end of the spring 29-15 secured to'thebag 28jat the respective opposite-ends of a'tape or reinforcing stitching 3| extending along the wall 'of the bag as also shown in Figure 2. For controlling the electric motor 24 there is suitably mounted on the casing, preferably on section 6 of the casing, an electric switch 32 and V the switch 32 may be of such a type as to be controlled in response to the swinging movement of the handle i9 so as to close when the handle I9 is in a position for use in pushing the cleaner over the surface to be cleaned. In this connection it will also be understood that the switch 32 Secured to and extending downwardly from the underside of the casing section] is a rack segment 31 with which a rack pin 38 extending laterally from the wheel support 34 coacts to secure the casing 5 in a position of adjustment securing the cleaner nozzle l2 at a selected working height. with respect, for example, to the floor covering being cleaned.

To facilitate such adjustment the wheel carrier or support 34 is provided at the axle-equipped end thereof with a rearwardly extending foot pedal'39as shown.

In connection with the above it will be noted that in the forms of the invention shown in Figures 1 and 5, the casing section 1 at the rear and small end thereof is provided with an opening through which the air may pass into the surrounding atmosphere. To filter the air so passing from the casing a suitable filtering assembly isprovided. In this instance the filtering assembly is shown as consisting of a frame 40 that is of such a shape as to form substantially a continua- .tionof-the casing section 1.

The frame 40 is hinged to the casing section 1 as at 41 and suitable latch means 42 is provided for securing the frame in proper position with respect to the casing.

, Arranged in the frame 40 is a'filtering element 43 which may be of any suitable character for the purpose intended and which will serve to filter the air. as it discharges from the casing of the vacuum cleaner.

If desired, and as shown in Figure 4 casing section 'imay be closed at its rear and minor end; the-filter assembly 40, 43 dispensed with, and the casing section}! perforated as indicated generally at 44 to permit the air to escape therefrom and-into the surrounding atmosphere.

Conventional blower tools may be connected tothe machine at the frame 40.

Also, and if desired, and as shown in Figure 5, there may be provided in the bottom of the easing section 1 an outlet for dirt and other. accumulations, and for such outlet there is provided a screen closure 45.

The closure 45 is in the form of a slide closure and operates between spaced parallel guide rails or tracks 46 provided therefor as shown.

Also in accordance with the present invention, the cleaner is equipped with a sweeper or beater brush 41 which may or may not be used as found desirable. v

The brush 4'! is positioned within the elongatedpart'oi the nozzle [2, with the shaft 48 of the brush being Journaled in the end walls |2a of the nozzle.

A belt pulley49 is fixed to the shaft 40 of the brush'intermediate the ends of said shaft and is adapted to be operated from the shaft 25 ofv the electric motor by means of a belt 50 that is trained over the pulley 49, aforementioned, and a pulley 5| provided on the front end of the motor or armature shaft 25 as shown in Figure 2.

Access to the belt 50 may be had through the front wall of the nozzle l2 through the medium of an opening provided for that purpose in said wall. For said opening a removable cover plate or plug 52 is'provided as shown.

Conventional vacuum tools may be attached to the machine by insertion in opening covered by plug 52.

Also to facilitate carrying of the cleaner bodily there is provided on the top of the section I of the casing of the cleaner a suitable handle or handgrip 53.

It will thus be seen that I have provided a suction or vacuum cleaner that may be readily and easily handled, can be used to advantage for emcient cleaning on floor coverings, furniture and the like, and also one in which access to the dust bag may be readily had. In this latter connection it will be seen that access to the bag 28 is had by separating the sections 6 and 1, and by gripping the member 30 the bag28 may be bodily and partially withdrawn from the casing 1 to facilitate emptying the contents thereof. Spring 29 will serve to anchor the closed end of the bag within the casing section I and thus further facilitate the proper placement of the bag within the casing section 1 for further use.

It is believed that the many advantages of a suction cleaner embodying the features of the present invention will be had without further detailed description.

It will also be understood that while I have herein illustrated and described what is considered the preferred embodiment of the invention, I

\ am well aware that in actual practice minor changes may be made without departing from the spirit of the invention as hereinafter claimed.

Having thus described the invention what is claimed as new is:

In a vacuum cleaner of the character described, a hollow casing composed of-a pair of complemental sections including a motor section and a bag section each having interengaging means adapted for detachably securing the sections in rigidly assembled relation, a motor in the motor section having front and rear fans attached thereto at opposite ends of the motor for sucking air into the motor section and discharging the same into the bag section, and a support for the motor comprising horizontal and vertical rods ex tending transversely of the motor section and securing the motor in spaced relation to the walls of said motor section.
